•In the adjustment window, you see the direct filament image and the mirror image, which in most cases are shifted together.

•Focus the direct filament image with the col- lector (46.6).

•Use the adjusting buttons on the rear side of the lamp housing (46.2, 46.4) to pivot the lamp filament’s mirror image to the side or com- pletely out of the beam path. The lamp fila- ment’s focused image remains visible (Fig. 47).

•Adjust the direct filament image using the ad- justing knobs (46.1) and (46.5) so that the centering surface is halfway covered (Fig. 48).

•Then pivot the lamp filament’s mirror image with the adjusting knobs (46.2 and 4), and focus it using the reflector (46.3).

•Align the mirror image symmetrically to the fil- ament image (Fig. 49). To do so, use the adjust- ing knobs (46.2) and (46.4) again.

•Defocus the image with the collector head (46.6) until the filament image and mirror im- age are no longer recognizable and the image is uniformly illuminated.

•Exchange the reflector cube for lamp

adjustment for the original filter cube.
